FIELD OF THE INVENTION

The present invention relates to two-wheeled vehicles, such as bicycles and scooters and, more particularly, to a stabilization apparatus attached to the frame of a two-wheeled vehicle that stabilizes such vehicle during use.

BACKGROUND OF THE INVENTION

A bicycle is as pedal-driven vehicle with two wheels attached to a frame, one behind and in-line with respect to the other. A person who rides a bicycle is a cyclist or bicyclist. Bicycles were introduced in the early 19^(th) century, and are useful not only as simple transportation but also for recreation and fitness purposes. Scooters also have two wheels. However, unlike bicycles, scooters are motor-driven.

Because vehicles such as bicycles and scooters have two wheels, a bit of training and practice is required in order to ride such two-wheeled vehicles safely and efficiently. However, for uncoordinated people and people that suffer from balance problems or disorders riding bicycles and scooters is particularly dangerous and generally not recommended regardless of how much practice or training they have. In order to allow uncoordinated people and people with balance disorders to use two-wheeled vehicles, what is therefore needed is an improved stabilization apparatus useful in conjunction with a two-wheeled vehicle, such as bicycle and even a scooter, to provide such two-wheeled vehicle with improved stabilization during use to allow such two-wheeled vehicle to be safely, easily, and efficiently used by uncoordinated people and people challenged with balance disorders.

SUMMARY OF THE INVENTION

According to the principle of the invention, a vehicle assembly includes a two-wheeled vehicle having a front wheel positioned in front of an opposed rear wheel that is in-line with respect to the front wheel, and a stabilization apparatus including a front stabilizer assembly attached to the vehicle proximate to the front wheel, and a rear stabilizer assembly attached to the vehicle proximate to the rear wheel. The front stabilizer assembly includes a first pair of opposed wheels resiliently mounted to a first framework secured to the vehicle to resiliently interact with the ground on either side of the vehicle proximate to the front wheel over which the vehicle is ridden to stabilize the vehicle, and the rear stabilizer assembly includes a second pair of opposed wheels resiliently mounted to a second framework secured to the vehicle to resiliently interact with the ground on either side of the vehicle proximate to the rear wheel over which the vehicle is ridden to stabilize the vehicle. The two-wheeled vehicle is a bicycle in a preferred embodiment.

According to the principle of the invention, a vehicle assembly includes a two-wheeled vehicle including a frame having opposed first and second sides, opposed front and rear ends, and a front wheel mounted for rotation to the frame proximate to the front end of the frame positioned in front of an opposed rear wheel mounted for rotation to the frame proximate to the rear end of the frame and that is substantially in-line with respect to the front wheel. A first forward stabilizer wheel and a first rearward stabilizer wheel are each mounted to a first support assembly secured to the frame between the front and rear wheels. The first support assembly supports the first forward stabilizer wheel along the first side of the frame proximate to, and outboard of, the front wheel of the vehicle, and supports the first rearward stabilizer wheel along the first side of the frame proximate to, and outboard of, the rear wheel of the vehicle. A second forward stabilizer wheel and a second rearward stabilizer wheel are each mounted to a second support assembly secured to the frame between the front and rear wheels. The second support assembly supports the second forward stabilizer wheel along the second side of the frame proximate to, and outboard of, the front wheel of the vehicle so as to oppose the first forward stabilizer wheel, and supports the second rearward stabilizer wheel along the second side of the frame proximate to, and outboard of, the rear wheel of the vehicle so as to oppose the first rearward stabilizer wheel. The first and second forward stabilizer wheels are positioned to interact with the ground over which the vehicle is driven along the first and second sides of the frame proximate to the front wheel of the vehicle to stabilize the vehicle proximate to the front end of the frame of the vehicle. The first and second rearward stabilizer wheels are positioned to interact with the ground over which the vehicle is driven along the first and second sides of the frame proximate to the rear wheel of the vehicle to stabilize the vehicle proximate to the rear end of the frame of the vehicle. The front wheel rotates about a first axis of rotation, the rear wheel rotates about a second axis of rotation, the first and second forward stabilizer wheels are positioned proximate to the first axis of rotation of the front wheel, and the first and second rearward stabilizer wheels are positioned proximate to the second axis of rotation of the rear wheel. The first forward stabilizer wheel is substantially in-line with respect to the first rearward stabilizer wheel. The second forward stabilizer wheel is substantially in-line with respect to the second rearward stabilizer wheel. In a particular embodiment, the vehicle assembly is fashioned with an axle, having a first end portion positioned proximate to the first side of the frame of the vehicle and an opposed second end portion positioned proximate to the second side of the frame of the vehicle, which is mounted to a connector assembly affixed to the frame of the vehicle between the front and rear wheels. The first support assembly is mounted to the first end portion of the axle, and the second support assembly mounted to the second end portion of the axle. The first support assembly is further mounted to the first end portion of the axle for pivotal movement, and the second support assembly is further mounted to the second end portion of the axle for pivotal movement. The axle is mounted to the connector assembly for movement between a raised position toward the frame of the vehicle away from the ground over which the vehicle is driven, and a lowered position away from the frame of the vehicle toward the ground over which the vehicle is driven. The first forward and rearward stabilizer wheels are each mounted to the first support assembly for swiveling movement, and the second forward and rearward stabilizer wheels are each mounted to the second support assembly for swiveling movement.

According to the principle of the invention, a vehicle assembly includes a two-wheeled vehicle including a frame having opposed first and second sides, opposed front and rear ends, and a front wheel mounted for rotation to the frame proximate to the front end of the frame positioned in front of an opposed rear wheel mounted for rotation to the frame proximate to the rear end of the frame and that is substantially in-line with respect to the front wheel. A member is carried by the frame of the vehicle between the front and rear wheels and has first and second end portions disposed adjacent to the respective first and second sides of the frame. A wheeled stabilizer assembly is carried by each of the first and second end portions of the member to wheelingly interact with the ground over which the vehicle is driven along the first and second sides of the frame proximate to the front and rear wheels of the vehicle to stabilize the vehicle as the vehicle is driven over the ground. The member is mounted to the frame of the vehicle for movement between a raised position of the first and second end portions toward the frame of the vehicle away from the ground over which the vehicle is driven, and a lowered position of the first and second end portions away from the frame of the vehicle toward the ground over which the vehicle is driven. The wheeled stabilizer assemblies each include a framework having an attached forward stabilizer wheel disposed proximate the front wheel of the vehicle and an attached rearward stabilizer wheel disposed proximate to the rear wheel of the vehicle. The forward stabilizer wheel is substantially in-line with respect to rearward stabilizer wheel in each of the wheeled stabilizer assemblies. The wheeled stabilizer assemblies are each mounted for pivotal movement to the respective first and second end portions of the member.

According to the principle of the invention, a vehicle assembly includes a two-wheeled vehicle including a frame having opposed first and second sides, opposed front and rear ends, and a front wheel mounted for rotation to the frame proximate to the front end of the frame positioned in front of an opposed rear wheel mounted for rotation to the frame proximate to the rear end of the frame and that is substantially in-line with respect to the front wheel. A member is carried by the frame of the vehicle between the front and rear wheels and has first and second end portions disposed adjacent to the respective first and second sides of the frame. First and second wheeled stabilizer assemblies are carried by the first and second end portions, respectively, of the member to wheelingly interact with the ground over which the vehicle is driven along the first and second sides of the frame proximate to the front and rear wheels of the vehicle to stabilize the vehicle as the vehicle is driven over the ground. The first wheeled stabilizer assembly includes a first elongate support member disposed proximate to and extending along the first side of the frame of the vehicle, the first elongate support member including a first leading end directed toward the front wheel of the vehicle and a first trailing end directed toward the rear wheel of the vehicle, a first front arm attached to the first leading end of the first elongate support member and extending outwardly therefrom with respect to the first elongate support member and the first side of the frame of the vehicle to a first forward wheeled end disposed proximate to and outboard of the front wheel of the vehicle, and a first rear arm attached to the first trailing end of the first elongate support member and extending outwardly therefrom with respect to the first elongate support member and the first side of the frame of the vehicle to a first rearward wheeled end disposed proximate to and outboard of the rear wheel of the vehicle. The second wheeled stabilizer assembly includes a second elongate support member disposed proximate to and extending along the second side of the frame of the vehicle, the second elongate support member including a second leading end directed toward the front wheel of the vehicle and a second trailing end directed toward the rear wheel of the vehicle, a second front arm attached to the second leading end of the second elongate support member and extending outwardly therefrom with respect to the second elongate support member and the second side of the frame of the vehicle to a second forward wheeled end disposed proximate to and outboard of the front wheel of the vehicle, and a second rear arm attached to the second trailing end of the second elongate support member and extending outwardly therefrom with respect to the second elongate support member and the second side of the frame of the vehicle to a second rearward wheeled end disposed proximate to and outboard of the rear wheel of the vehicle. The first elongate support member is substantially parallel with respect to the second elongate support member. The member is mounted to the frame of the vehicle for movement between a raised position of the first and second end portions toward the frame of the vehicle away from the ground over which the vehicle is driven, and a lowered position of the first and second end portions away from the frame of the vehicle toward the ground over which the vehicle is driven. The first forward wheeled end of the first wheeled stabilizer assembly is substantially in-line with respect to the first rearward wheeled end of the first wheeled stabilizer assembly, and the second forward wheeled end of the second wheeled stabilizer assembly is substantially in-line with respect to the second rearward wheeled end of the second wheeled stabilizer assembly.

According to the principle of the invention, a vehicle assembly includes a vehicle including a frame having opposed first and second sides, opposed front and rear ends, and a front wheel mounted for rotation to the frame proximate to the front end of the frame positioned in front of an opposed rear wheel mounted for rotation to the frame proximate to the rear end of the frame and that is substantially in-line with respect to the front wheel. A first forward stabilizer and a second forward stabilizer are each mounted to a fixture mounted to the frame. The fixture supports the first forward stabilizer along the first side of the frame proximate to, and outboard of, the front wheel of the vehicle. The fixture supports the second forward stabilizer along the second side of the frame proximate to, and outboard of, the front wheel of the vehicle so as to oppose the first forward stabilizer. The fixture is movable between a raised position toward the frame of the vehicle away from the ground over which the vehicle is driven, and a lowered position away from the frame of the vehicle toward the ground over which the vehicle is driven. A lock assembly is coupled between the frame and the fixture, and in the lowered position of the fixture the lock assembly is adjustable between a locked position locking the fixture in the lowered position preventing the fixture from moving from the lowered position to the raised position, and an unlocked position releasing the fixture in the lowered position allowing the fixture to move from the lowered position to the raised position. The first and second forward stabilizers are positioned to interact with the ground over which the vehicle is driven, along the first and second sides of the frame proximate to the front wheel of the vehicle, to stabilize the vehicle proximate to the front end of the frame of the vehicle. A first rearward stabilizer is mounted to a first support member mounted to the frame. A second rearward stabilizer mounted to a second support member mounted to the frame. The first support member supports the first rearward stabilizer along the first side of the frame proximate to, and outboard of, the rear wheel of the vehicle. The second support member supports the second rearward stabilizer along the second side of the frame proximate to, and outboard of, the rear wheel of the vehicle so as to oppose the first rearward stabilizer. The first and second rearward stabilizers are positioned to interact with the ground over which the vehicle is driven, along the first and second sides of the frame proximate to the rear wheel of the vehicle, to stabilize the vehicle proximate to the rear end of the frame of the vehicle. In a particular embodiment, the first support member is independently movable between a raised position toward the frame of the vehicle away from the ground over which the vehicle is driven, and a lowered position away from the frame of the vehicle toward the ground over which the vehicle is driven.

DETAILED DESCRIPTION

Turning now to the drawings, in which like reference characters indicate corresponding elements throughout the several views, attention is first directed to FIG. 1 in which there is seen a bicycle 10 including a frame 11 having a front or forward end denoted generally at 12, and an opposed rear or rearward end denoted generally at 13. Front end 12 of frame 11 may be considered the front end of bicycle 10, and rear end 13 of frame 11 may be considered the rear end of bicycle 10. Frame 11 consists of a top tube 20 and an opposed down tube 21 that extend between front 12 and rear 13. Top and bottom tubes 20 and 21 are connected at front 12 with a head tube 22, and are connected at rear 13 with an upright seat tube 23. Opposed seat stays 24 (only one shown) are connected to top tube 20 and seat tube 23 proximate to rear 13 of frame 11, and opposed chain stays 25 (only one shown) are connected to bottom tube 21 and seat tube 23 at rear 13 of frame 11. Seat stays 24 extend downwardly and rearwardly from top tube 20 and seat tube 23, chain stays 25 extend rearwardly of bottom tube 21 and seat tube 23, and seat stays 24 and chain stays 25 meet and connect at rear 13 of frame 11 and are coupled to a rear hub 26 of a rear wheel 27.

At front 12 of frame 11, handlebars 30 are connected to head tube 22 with a headset 31 that is connected to the upper end of a fork stem (not shown) that extends downwardly through head tube 22 to front forks 32, which extend downwardly and terminate with free ends 33 connected to a front hub 34 of a front wheel 35. Front wheel 35 is positioned in front of rear wheel 27, and rear wheel 27 is in-line with respect to front wheel 35. A seat 40 is mounted to a seat post 41 that extends into and is rigidly connected to seat tube 23. Bicycle 10 is pedal-driven, and includes a pedal-driven drive train 50 consisting of pedals 51 (only one shown) attached to crank arms 52 (only one shown) rigidly connected to a bottom bracket 53 that is, in turn, rigidly connected to a chainring 54. An endless chain 55 concurrently encircles and operatively couples chainring 54 to cassette 56 formed in rear hub 26 to impart rotation to rear wheel 27 in response to rotation of chainring 54 made through a pedaling action applied to pedals 51, such as by a user seated on seat 40. Drive train 50 is a conventional form of a pedaled drive train commonly found among conventional bicycles.

Bicycle 10 is exemplary of a non-motorized two-wheeled vehicle, is entirely conventional and is generally representative of any one of a variety of commercially available bicycles. Accordingly, further details of bicycle not herein specifically disclosed will readily occur to those having ordinary skill and are not discussed in further detail.

In accordance with the principle of the invention, bicycle 10 is formed with a stabilization apparatus denoted generally at 60. The combination of bicycle 10 and stabilization apparatus 60 forms a vehicle or bicycle assembly according to the principle of the invention. Apparatus 60 consists of a main or front stabilizer assembly denoted at 61, and an opposed trailing or rear stabilizer assembly denoted at 62. Assemblies 61 and 62 are wheeled assemblies which are attached to bicycle 10 and, more particularly, to frame 11 of bicycle 10. Assemblies 61 and 62 interact with the ground and cooperate together to stabilize bicycle 10 during use to assist a user using bicycle 10 in the normal manner in balancing bicycle, and this is particularly useful for users that suffer from balance disorders or who are uncoordinated. Front assembly 61 is attached to bicycle 10 proximate to front 12 of bicycle 10 forwardly of bottom bracket 53, and rear assembly 62 is attached to bicycle 10 proximate to rear 13 of bicycle 10 rearwardly of bottom bracket 53.

Referencing FIG. 2, assembly 61 consists of framework formed by opposed front stays 70 and 71 rigidly affixed to frame 11. In the present embodiment, the framework formed by front stays 70 and 71 is secured to top and bottom tubes 20 and 21 of frame 11. Stays 70 and 71 are fashioned of strong, rigid material, such as steel, aluminum, carbon fiber, or the like, are located on either side of top and bottom tubes 20 and 21 of frame 11, and are clamped together to clamp onto and embrace top and bottom tubes 20 and 21 with fasteners 74, which may be rivets, nut-and-bolt assemblies, or the like. Stays 70 and 71 extend downwardly with respect to top and bottom tubes 20 and 21 of frame 11, and terminate with free ends 70A and 71A rigidly affixed, with welding or with fasteners such as rivets or screws or nut-and-bolt assemblies or the like, to a support 80, which, as seen in FIG. 1, is located just rearwardly of front wheel 35 of bicycle 10 and forwardly of bottom bracket 53.

Support 80 is elongate, substantially horizontal, has opposed ends 81 and 82, and, like stays 70 and 71, is preferably fashioned of strong, rigid material, such as steel, aluminum, carbon fiber, or the like. Elongate flexible arms 84 and 85 are attached at either end of support 80. Arm 84 has a proximal end 84A affixed, with welding or with fasteners such as rivets or screws or nut-and-bolt assemblies or the like, to support 80 proximate to end 81 of support 80, and extends rearwardly of support 80, and front wheel 35 of bicycle 10 as shown in FIG. 1, to a distal end 84B journaled to a wheel 87. Arm 85 has a proximal end 85A affixed, with welding or with fasteners such as rivets or screws or nut-and-bolt assemblies or the like, to support 80 proximate to end 82 of support 80, and extends rearwardly of support 80, and front wheel 35 of bicycle 10 as shown in FIG. 1, to a distal end 85B journaled to a wheel 88. Wheels 87 and 88 are located at either end of support 80, and this is best illustrated in FIG. 4, which is a fragmented, front elevation view of assembly 62, FIG. 5, which is a fragmented, rear elevation view of assembly 62, and FIG. 6, which is a fragmented, bottom plan view of assembly 62. Wheels 87 and 88 are also located on either side of frame 11 of bicycle 10 as shown in FIG. 1.

Wheels 87 and 88 are conventional caster wheels or other like or similar wheel form, and conventional hubs 87A and 88A are used to journal wheels 87 and 88 to distal ends 84B and 85B of arms 84 and 85, respectively, as best illustrated in FIG. 6. Arms 84 and 85 are preferably formed of flat strips of spring steel, or other flexible and resilient material or combination of materials. The flexible, resilient character of arms 84 and 85 biases wheels 87 and 88 into engagement against the ground over which bicycle 10 is ridden and permits wheels 87 and 88 to interact with the ground over which bicycle 10 is ridden and reciprocally displace with respect to the ground and bicycle 10 as bicycle 10 is used in the normal manner. As a matter of illustration and reference, FIG. 3 is a side elevation view of assembly 61 illustrating arm 84 attached between wheel 87 and support 80, whereby the double, arcuate arrowed line A is indicative of the reciprocal movement of wheel 87 provided by arm 84.

Referencing FIG. 7, assembly 62 consists of framework formed by opposed rear stays 90 and 91 rigidly affixed to frame 11. In the present embodiment, the framework formed by rear stays 90 and 91 is attached to seat stays 24 and chain stains 25 of frame 11. Stays 90 and 91 are fashioned of strong, rigid material, such as steel, aluminum, carbon fiber, or the like, are located on either side of the respective seat stays 24 and chain stays 25 of frame 11, and are clamped together to clamp onto and embrace seat stays 24 and chain stays 25 with fasteners 94, which may be rivets, nut-and-bolt assemblies, or the like. Stays 90 and 91 extend downwardly with respect to seat stays 24 and chain stays 25 of frame 11, and terminate with free ends 90A and 91A rigidly affixed, with welding or with fasteners such as rivets or screws or nut-and-bolt assemblies or the like, to a support 100, which, as shown in FIG. 1, is located just forwardly of rear wheel 27 under and opposing bottom bracket 53.

Support 100 is elongate, substantially horizontal, has opposed ends 101 and 102, and, like stays 90 and 91, is preferably fashioned of strong, rigid material, such as steel, aluminum, carbon fiber, or the like. Elongate flexible arms 104 and 105 are attached at either end of support 100. Arm 104 has a proximal end 104A affixed, with welding or with fasteners such as rivets or screws or nut-and-bolt assemblies or the like, to support 100 proximate to end 101 of support 100, and extends rearwardly of support 100, and toward rear wheel 27 as shown in FIG. 1, to a distal end 104B journaled to a wheel 107. Arm 105 has a proximal end 105A affixed, with welding or with fasteners such as rivets or screws or nut-and-bolt assemblies or the like, to support 100 proximate to end 102 of support 100, and extends rearwardly of support 100, and toward rear wheel 27 as shown in FIG. 1, to a distal end 105B journaled to a wheel 108. Wheels 107 and 108 are located at either end of support 100, and this is best illustrated in FIG. 9, which is a fragmented, front elevation view of assembly 62, FIG. 10, which is a fragmented, rear elevation view of assembly 62, and FIG. 11, which is a fragmented, bottom plan view of assembly 62. Wheels 107 and 108 are also located on either side of frame 11 of bicycle 10 as shown in FIG. 1.

Wheels 107 and 108 are conventional caster wheels or other like or similar wheel form, and conventional hubs 107A and 108A are used to journal wheels 107 and 108 to distal ends 104B and 105B of arms 104 and 105, respectively, as best illustrated in FIG. 11. Arms 104 and 105 are preferably formed of flat strips of spring steel, or other flexible and resilient material or combination of materials. The flexible, resilient character of arms 104 and 105 biases wheels 107 and 108 into engagement with the ground over which bicycle 10 is ridden and permits wheels 107 and 108 to interact with the ground over which bicycle 10 is ridden and to reciprocally displace with respect to the ground and bicycle 10 as bicycle 10 is used in the normal manner. As a matter of illustration and reference, FIG. 8 is a side elevation view of assembly 62 illustrating arm 104 attached between wheel 107 and support 100, whereby the double, arcuate arrowed line B is indicative of the reciprocal movement of wheel 107 provided by arm 104.

Wheels 87 and 88 of assembly 61 define two wheeled contact points of stabilization apparatus 60 proximate to front end 12 of bicycle 10 on either side of frame 11 and front wheel 35 of bicycle 10, and wheels 107 and 108 of assembly 62 define two wheeled contact points of stabilization apparatus 60 proximate to rear end 13 of bicycle 10 on either side of frame 11 and rear wheel 27 of bicycle 10. As such, wheels 87, 88, 107, and 108 of stabilization apparatus 60 form four wheeled contact points, two on either side of bicycle 10, to stabilize bicycle 10 during the normal use thereof as bicycle is ridden over the ground. Wheels 87 and 107 on one side of bicycle 10 and wheels 88 and 108 on the opposing side of bicycle 10 form a four-point wheeled footprint, whereby wheels 87, 88, 107, and 108 engage against and wheelingly interact with the ground over which bicycle 10 is ridden stabilizing bicycle 10 during the normal use thereof to assist users that are uncoordinated or may suffer from a balance disorder in safely riding bicycle 10. As previously explained, the flexible, resilient character of arms 84 and 85 biases wheels 87 and 88 into engagement against the ground over which bicycle 10 is ridden and permits wheels 87 and 88 to interact with the ground over which bicycle 10 is ridden and reciprocally displace with respect to the ground and bicycle 10 as bicycle 10 is used in the normal manner, the flexible, resilient character of arms 104 and 105 biases wheels 107 and 108 into engagement with the ground over which bicycle 10 is ridden and permits wheels 107 and 108 to interact with the ground over which bicycle 10 is ridden and to reciprocally displace with respect to the ground and bicycle 10 as bicycle 10 is used in the normal manner. Moreover, the flexible, resilient character of arms 84 and 85 not only biases wheels 87 and 88 into engagement against the ground over which bicycle 10 is ridden but also permit wheels 87 and 88 to reciprocate with respect to bicycle 10 and the ground over which bicycle 10 is ridden to allow bicycle 10 to be leaned somewhat to each side to allow bicycle 10 to be easily turned to the left and to the right with ease while ensuring wheels 87 and 88 remain in contact with the ground to provide the required stabilization, in accordance with the principle of the invention. Similarly, the flexible, resilient character of arms 104 and 105 not only biases wheels 107 and 108 into engagement against the ground over which bicycle 10 is ridden but also permit wheels 107 and 108 to reciprocate with respect to bicycle 10 and the ground over which bicycle 10 is ridden to allow bicycle 10 to be leaned somewhat to each side to allow bicycle 10 to be easily turned to the left and to the right with ease while ensuring wheels 107 and 108 remain in contact with the ground to provide the required stabilization, in accordance with the principle of the invention.

The frameworks of the front and rear stabilizer assemblies 61 and 62 can be secured to frame 11 at any suitable location and in any way suitable to rigidly secure them in place so as to operate in accordance with the teachings provided by this specification. Also, FIG. 12 is a side elevation view of an alternate embodiment of a stabilizer assembly 110 for use with a stabilization apparatus constructed and arranged in accordance with the principle of the invention. In common with stabilizer assembly 61, stabilizer assembly 110 shares the front stays (only stay 70 is depicted), support 80, and the wheels attached to support 80 with the arms (only wheel 87 and arm 84 are depicted). In assembly 110, a wheel 111, such as conventional caster wheel or other wheel form like that of wheel 87, is journaled with a conventional hub 112 to support 80. In this embodiment, wheel 111 is available to make wheeled contact with the ground over which the bicycle to which assembly 110 is attached to is ridden when the bicycle is turned too far to the left or to the right, and this provides additional stabilization. Assembly 110 in FIG. 12 has one wheel 111 journaled to support 80, and more can be journaled to support 80 as may be desired. Stabilizer assembly 62 of stabilization apparatus 60 may be similarly modified according to the assembly depicted in FIG. 12.

FIG. 13 is a front elevation view of an alternate embodiment of a stabilizer assembly 120 for use with a stabilization apparatus constructed and arranged in accordance with the principle of the invention. In common with stabilizer assembly 61, stabilizer assembly 110 shares the front stays 70 and 71 and attached arm support 80. In this embodiment an elongate rigid extension 121 is affixed to end 81 of arm support 80, and an elongate rigid extension 122 is affixed to end 82 of arm support 80. Extensions 121 and 122 extend outwardly with respect to ends 81 and 82, respectively, of arm support 80, and terminate with outer ends 121A and 122A, respectively. Arm 84 and wheel 87 are attached at end 121A of extension 121, and arm 85 and wheel 88 are attached at end 122A of extension 122. In this embodiment, extensions 121 and 122 provide a broader footprint of wheels 87 and 88 for even further increased stabilization as compared to the narrower footprint of wheels 87 and 88 in assembly 61. Stabilizer assembly 62 of stabilization apparatus 60 may be similarly modified according to the assembly depicted in FIG. 12.

FIG. 14 is a fragmented, side elevation view of a stay 130 for use with a stabilizer assembly of a stabilization apparatus constructed and arranged in accordance with the principle of the invention, in which portions of stay 130 are cutaway from illustrative purposes. Stay 130 can be used in place each front stay of assembly 61, and/or each rear stay of assembly 62. In this embodiment, stay 130 is formed by a pair of reciprocally mounted elongate stay members 131 and 132 including a spring 133 formed there between that acts against stay members 131 and 132 biasing them apart. Stay members 131 and 132 reciprocate with respect to each other allowing stay 130 to assume shortened and lengthened conditions or positions as the bicycle having a stabilizer assembly incorporating stay 130 is turned to the left and to the right, and spring 133 functions to urge stay 130 into its lengthened condition or position to ensure the stabilization wheels associated with stay 130 remain in contact with the ground over which a bicycle is ridden. The embodiment in FIG. 14 is exemplary of a reciprocating stay assembly, and other reciprocating mechanisms can be used in other embodiments, such as pneumatic reciprocating stay members, hydraulic reciprocating stay members, etc.

Stabilization apparatus 60 is disclosed in connection with bicycle 10, which is exemplary of a non-motorized two-wheeled vehicle incorporating a front wheel positioned in front of an opposed rear wheel that is in-line with respect to the front wheel. It is to be understood that a stabilization apparatus constructed and arranged in accordance with the principle of the invention is not only particularly useful with bicycles, but may also be utilized with equally-exemplary results with scooters and other like or similar motorized two-wheeled vehicles.

With continuing reference in relevant part to FIGS. 15 and 16, with respect to stabilizer assembly 260, elongate support member 271 is disposed proximate to and extends along the side 210A of frame 210 of bicycle 201 from leading end 272 directed toward front wheel 235 of bicycle 201 and trailing end 273 directed toward rear wheel 227, whereby front arm 275 attached to leading end 272 of elongate support member 271 extends outwardly therefrom with respect to elongate support member 271 and side 210A of frame 210 of bicycle 201 to wheeled end 277, which is disposed or otherwise located proximate to and outboard of front wheel 235 of bicycle 201, and rear arm 285 attached to trailing end 273 of elongate support member 271 extends outwardly therefrom with respect to elongate support member 271 and side 210A of frame 210 of bicycle 201 to wheeled end 287, which is disposed proximate to and outboard of rear wheel 227 of bicycle 201. With respect to stabilizer assembly 261, elongate support member 291 is disposed proximate to and extends along the side 210B of frame 210 of bicycle 201 from leading end 292 directed toward front wheel 235 of bicycle 201 and trailing end 293 directed toward rear wheel 229, whereby front arm 295 attached to leading end 292 of elongate support member 291 extends outwardly therefrom with respect to elongate support member 291 and side 210B of frame 210 of bicycle 201 to wheeled end 297, which is disposed or otherwise located proximate to and outboard of front wheel 235 of bicycle 201, and rear arm 305 attached to trailing end 293 of elongate support member 291 extends outwardly therefrom with respect to elongate support member 291 and side 210B of frame 210 of bicycle 201 to wheeled end 307, which is disposed proximate to and outboard of rear wheel 229 of bicycle 201.

When mounted to bicycle 201 according to this disclosure, stabilizer assemblies 260 and 261 are the mirror image of one another, and elongate support members 271 and 291 of stabilizer assemblies 260 and 261, respectively, oppose each and are substantially parallel with respect to each other, and are located toward sides 210A and 210B, respectively, of frame 210 and underneath frame 210 so as not to interfere with the normal pedaling action of pedals 251 and crank arms 251, which takes place along the outer side of elongate support members 271 and 291 between the leading ends 272 and 292 of elongate support members 271 and 291, respectively, and trailing ends 273 and 293 of elongate support members 271 and 291, respectively. Moreover, the pedaling action of pedals 251 and crank arms 251 takes place along the outer side of elongate support members 271 and 291 between front arms 275 and 295 of elongate support members 271 and 291, respectively, and rear arms 285 and 305 of elongate support members 271 and 291, respectively. With reference to FIG. 15, front wheel 235 of bicycle 201 rotates about an axis of rotation denoted at 390, rear wheel 227 rotates about an axis of rotation denoted at 391, front or forward stabilizer wheels 278 and 298 of stabilizer assemblies 260 and 261, respectively, are positioned proximate to axis of rotation 390 of front wheel 235, and rear or rearward stabilizer wheels 288 and 308 of stabilizer assemblies 260 and 261, respectively, are positioned proximate to axis of rotation 391 of rear wheel 227.

Of course, in the use of bicycle 201 in its normal manner with apparatus 202 attached thereto as explained in detail and as shown in FIGS. 15 and 16, stabilizer assemblies 260 and 261 are positioned to ensure that support assemblies 270 and 290 are oriented and positioned to ensure that front and rear wheels 235 and 227 of bicycle 201 and the four wheeled ends of stabilizer assemblies 260 and 261 concurrently interact with the ground over which bicycle 201 is driven to permit stabilizer assemblies 260 and 261 of apparatus 202 work in accordance with their intended purpose which is to cooperate together to stabilize bicycle 201 as it is driven over the ground by preventing bicycle 201 from tipping over on one side or the other. And so apparatus 202 is constructed, arranged, and sized to fit onto bicycle 201 to function in this way. The four wheeled ends of stabilizer assemblies 260 and 261 concurrently interact with the ground over which bicycle 201 is driven to form a four-point wheeled footprint that engage against and wheelingly interact with the ground over which bicycle 201 is ridden stabilizing bicycle 201 during the normal use thereof to assist users that are uncoordinated or may suffer from a balance disorder in safely riding bicycle 201.

Apparatus 202 is designed to be removably attached to any bicycle, and bicycles come in different sizes and shapes and have different clearances between the frame and the ground over which the bicycle is ridden. As such, connector assembly 262 is configured to permit adjustment of stabilizer assemblies 260 and 261 between a raised position toward frame 210 as shown in FIG. 22, and a lowered position away from frame 210 as shown in FIG. 24, and this reciprocal movement of stabilizer assemblies 260 and 261 is denoted generally by the double arrowed line C in FIGS. 22 and 24.

Movement of stabilizer assemblies 260 and 261 attached to connector assembly 262 secured to bicycle 201 between raised and lowered positions can be carried out through the adjustment of support fixture 321, which is mounted to base 330 for movement between a raised position toward frame 210 and away from the ground over which bicycle 201 is driven and a lowered position away from frame 210 and toward the ground over which bicycle 201 is driven, the adjustment of block 322, which is mounted to support fixture 321 for movement between a raised position toward frame 210 and away from the ground over which bicycle 201 is driven and a lowered position away from frame 210 and toward the ground over which bicycle 201 is driven, or through the adjustment of both the support fixture 321 and block 322.

Looking to FIG. 21, slots 352 through support fixture 321 are elongate and substantially vertically with respect to the ground over which bicycle 201 is ridden. When threaded fasteners 356 are loosened, support fixture 321 may be moved relative to base 330 between a raised position as shown in FIGS. 21 and 22 locating stabilizer assemblies 260 and 261 secured to member 323 secured to block 322 fastened to support fixture 321 at a raised position, and a lowered position as shown in FIGS. 23 and 24 locating stabilizer assemblies 260 and 261 secured to member 323 secured to block 322 fastened to support fixture 321 at a lowered position. Slots 352 are substantially equal in length, and the amount of travel of support fixture 321 between its raised and lowered positions is limited by the length of slots 352, which limit the travel of threaded fasteners 356 through slots 352 when support fixture 321 is moved between its raised and lowered positions. After support fixture 321 is disposed at a desired location, threaded fasteners 356 are tightened to secure support fixture 321 in place relative to base 330. Of course, movement of support fixture 321 between its raised and lowered positions results in the corresponding movement of axle or member 323 attached to support fixture 321 via block 322 between a raised position of end portions 323A and 323B toward frame 210 of bicycle 201 away from the ground over which bicycle 201 is driven, and a lowered position of end portions 323A away from frame 210 of bicycle 201 toward the ground over which bicycle 201 is driven. With stabilizer assemblies 260 and 261 attached to end portions 323A and 323B, respectively, it is to be understood that this movement of end portions 323A and 323B between raised and lowered positions through the movement of member 323 between raised and lowered positions provides corresponding movement of stabilizer assemblies 260 and 261 between raised and lowered positions.

Looking back to FIG. 17, block 322 that carries member 323 is formed with the pair of threaded openings 360, which are aligned with a corresponding pair of the openings 353 formed into and through support fixture 321 and secured in place with threaded fasteners 361, and this permits movement of block 321 relative to support fixture 321 between a raised position as shown in FIGS. 23 and 24 locating stabilizer assemblies 260 and 261 secured to member 323 secured to block 322 fastened to support fixture 321 at corresponding raised position, and a lowered position as shown in FIGS. 21 and 22 locating stabilizer assemblies 260 and 261 secured to member 323 secured to block 322 fastened to support fixture 321 at a corresponding lowered position. In FIGS. 21 and 22, threaded fasteners 361 are threadably received by threaded openings 360 (FIG. 17) in block 322 securing block 322 to support fixture 321, and threaded fasteners 361 are received in a corresponding lower pair of openings 353 (FIG. 17) in support fixture 321 that corresponds to the lowered position of block 32. In FIGS. 23 and 24, threaded fasteners 361 are threadably received by threaded openings 360 (FIG. 17) in block 322 securing block 322 to support fixture 321, and threaded fasteners 361 are received in a corresponding upper pair of openings 353 (FIG. 17) in support fixture 321 that corresponds to the raised position of block 32. Of course, movement of block 322 between its raised and lowered positions results in the corresponding movement of axle or member 323 carried by block 322 between a raised position of end portions 323A and 323B toward frame 210 of bicycle 201 away from the ground over which bicycle 201 is driven, and a lowered position of end portions 323A away from frame 210 of bicycle 201 toward the ground over which bicycle 201 is driven. With stabilizer assemblies 260 and 261 attached to end portions 323A and 323B, respectively, it is to be understood that this movement of end portions 323A and 323B between raised and lowered positions through the movement of block 322 between raised and lowered positions provides corresponding movement of stabilizer assemblies 260 and 261 between raised and lowered positions.

Looking back in relevant part to FIGS. 15 and 16, axle or member 323 extends transversely with respect to frame 210 of bicycle 201 between front and rear wheels 235 and 227, and defines an axis 395 therethrough from end portion 323A to end portion 323B, which is substantially parallel with respect to axis 390 of rotation of front wheel 235, axis 391 of rotation of rear wheel 227, and axis 253A of rotation of bottom bracket 253 that is located above and that opposes axis 395 of axle or member 323. Axis 253A and axis 395 reside in a substantially vertical plane with respect to the length of bicycle 201 from its front end to its rear end. Support assembly 270 held by end portion 323A of axle or member 323 is free to pivot about axis 395 of axle or member 323 to permit stabilizer assembly 260 to freely pivotally displace as needed as bicycle 201 as driven over the ground. Support assembly 290 held by end portion 323B of axle or member 323 is, like support assembly 270, free to pivot about axis 395 of axle or member 323 to permit stabilizer assembly 261, like stabilizer assembly 260, to freely pivotally displace as needed as bicycle 201 is driven over the ground. Preferably, there is sufficient clearance between end portion 323A of axle or member 323 and opening 271A (FIG. 17) formed in support assembly 270 through which end portion 323A is received to permit the pivotal movement of stabilizer assembly 260 with respect to end portion 323A of axle or member 323. Likewise, there is preferably sufficient clearance between end portion 323B of axle or member 323 and opening 291A (FIG. 17) formed in support assembly 290 through which end portion 323B is received to permit the pivotal movement of stabilizer assembly 261 with respect to end portion 323B of axle or member 323.

Attention is now directed to FIG. 25, which is a perspective view of an alternate embodiment of a stabilization apparatus 500 constructed and arranged in accordance with the principle of the invention, and to FIG. 26, which is an exploded perspective view of stabilization apparatus 500 first illustrated in FIG. 25. Stabilization apparatus 500 is constructed of the same material or combination of materials described in connection with the previous stabilization apparatus embodiments, and, in general, includes a forward or front stabilizing assembly 501, an opposed rearward or rear stabilizing assembly 502, a connector assembly 503, and a lock assembly 504. Connector assembly 503 is used to connect forward and rearward stabilizing assemblies 501 and 502 to a vehicle to be stabilized so as to form a vehicle assembly which is shown and denoted generally at 540 in FIGS. 29-31 and 34-39. Forward stabilizing assembly 501 extends in a forward direction from connector assembly 503 to provide vehicle stabilization at a front end of a vehicle to be stabilized, and rearward stabilizing assembly 502 extends in the opposite rearward direction from connector assembly 503 to provide vehicle stabilization at a rear end of a vehicle to be stabilized.

Referring to FIGS. 29 and 30, the vehicle to be stabilized in conjunction with stabilization apparatus 500 is a bicycle denoted at 541, which is shown as it would appear fitted with stabilization apparatus 500 forming vehicle assembly 540 stabilized by stabilization apparatus 500 according to the principle of the invention. In common with bicycle 201 previously discussed, and referring to FIGS. 29 and 30 in relevant part, bicycle 541 shares the usual frame 210, front or forward end 211, rear or rearward end 212, opposed sides 210A and 210B, top tube 220, bottom or down tube 221, head tube 222, seat tube 223, seat stays 224, chain stays 225, rear hub 226 and rear wheel 227, handlebars 230, headset 231, front forks 232 having free ends 233 connected to front hub 234 of front wheel 235 that is positioned in front of rear wheel 227, which is substantially in-line with respect to front wheel 235 as is typical and well-known with a conventional bicycle. Like bicycle 201, bicycle 541 additionally shares the usual seat 240, seat post 241, a drive train 250 consisting of pedals 251, crank arms 252, bottom bracket 253, the usual front chainrings denoted at 254, endless chain 255, and rear cassette 256. In common with bicycle 201, in bicycle 541 pedals 251 and crank arms 252 rotate about axis 253A of bottom bracket 253. Front wheel 235 of bicycle 341 rotates about an axis of rotation denoted at 390, and rear wheel 227 rotates about an axis of rotation denoted at 391.

Bicycle 541 is a form of a vehicle. Moreover, bicycle 541 is exemplary of a non-motorized two-wheeled vehicle, is entirely conventional and is generally representative of any one of a variety of commercially available bicycles, which, in the present example, is a variety of bicycle commonly referred to as a mountain bike. Accordingly, further details of bicycle 541 not herein specifically disclosed will readily occur to those having ordinary skill and are not discussed in further detail.

Referring in relevant part to FIGS. 25, 26, 27 and 28, forward and rearward stabilizing assemblies 501 and 502 are wheeled or wheel assemblies in the present embodiment characterized in that they have wheeled ends that wheelingly interact with the ground over which a vehicle to be stabilized is driven, which, in this example, is bicycle 541 as referenced in FIGS. 29 and 30.

Forward stabilizing assembly 501 consists of a fixture 510 that includes diametrically opposed, elongate, coextensive and spaced-apart forward support members 511A and 511B, which are the minor image of one another and are identical in every respect and bear common reference numerals. Forward support members 511A and 511B each include an elongate proximal arm 515 having opposed inner and outer ends 515A and 515B, and an elongate distal arm 516 having opposed inner and outer ends 516A and 516B. Inner end 515A is formed with a coupling in the form of a collar 517, and inner end 515A is considered a coupling end in the form of a collared end. Collars 517 of forward support members 511A and 511B are used to mount or attach fixture 510 to connector assembly 503. Inner end 516A of distal arm 516 is attached to outer end 515B of proximal arm 515, and extends angularly outwardly therefrom with respect to proximal arm 515 to outer end 516B that is formed with an attached stabilizer, which, in the present embodiment, is a wheel 518 that extends downwardly from outer end 516B. With outer end 516B formed with stabilizer wheel 518, outer end 516B is considered a stabilizer/stabilizing end in the form of a wheeled end and each of the forward support members 511A and 511B is, therefore, considered to be a wheeled forward support member. Stabilizer wheel 518 is conventional caster wheel, which swivels and rotates. Proximal arms 515 are diametrically opposed and are parallel and spaced-apart and extend concurrently in the same forward direction from collars 517 at inner ends 515A to outer ends 515B attached to inner ends 516A of distal arms 516, which are diametrically opposed and extend forwardly and diverge angularly outwardly away from one another in the same forwardly direction from inner ends 516A to the wheeled ends of forward stabilizing assembly 501, namely, outer ends 516B formed with attached and diametrically opposed wheels 518, respectively. A plate or brace 519 is positioned between, and is rigidly affixed via welding directly to proximal arms 515 between inner ends 515A and outer ends 515B of proximal arms 515, which rigidly affixes or otherwise rigidly attaches forward support member 511A to forward support member 511B.

Rearward stabilizing assembly 502 includes diametrically opposed, elongate, coextensive and spaced-apart rearward support members 530A and 530B, which are the minor image of one another and are identical in every respect and bear common reference numerals. Rearward support members 530A and 530B each include an elongate proximal arm 531 having opposed inner and outer ends 531A and 531B, and an elongate distal arm 532 having opposed inner and outer ends 532A and 532B. Inner end 531A is a coupling end as it is formed with a coupling in the form of an enlargement or head 534 formed with opposed upper and lower through holes 534A and 534B. Upper through hole 534A is a guide hole and is elongated with respect to lower through hole 534B and is downwardly arcuate or curved in a vertical direction toward lower through hole 534B. Head 534 is a coupling, and each head 534 is used to pivotally connect, mount or attach a corresponding one of the rearward support member 530A and 530B to connector assembly 503. Inner end 532A of distal arm 532 is attached to outer end 531B of proximal arm 531, and extends angularly outwardly therefrom with respect to proximal arm 531 to outer end 532B that is formed with an attached stabilizer, which, in the present embodiment, is a wheel 528 that extends downwardly from outer end 532B. With outer end 532B formed with stabilizer wheel 538, outer end 532B is considered a stabilizer/stabilizing end in the form of a wheeled end and each of rearward support members 530A and 530B is, therefore, considered to be a wheeled rearward support member. Stabilizer wheel 528 is conventional caster wheel, which swivels and rotates. Proximal arms 531 are diametrically opposed and are parallel and spaced-apart and extend concurrently in the same rearward direction from heads 534 at inner ends 531A to outer ends 531B attached to inner ends 532A of distal arms 532, which are diametrically opposed and extend rearward and angle outwardly away from one another in the same rearward direction from inner ends 532A to outer ends 532B formed with attached and diametrically opposed wheels 528, respectively.

As stated above, bicycle 541 is formed with stabilization apparatus denoted generally at 500, and the combination of bicycle 541 and stabilization apparatus 500 forms a vehicle, a bicycle assembly, or a vehicle assembly 540 according to the principle of the invention. Connector assembly 503 is used to connect stabilization apparatus 500 to bicycle 541, and connector assembly 503 will now be discussed in detail with reference in relevant part to FIGS. 25, 26, 27, and 28.

Connector assembly 503 includes a bracket 550, a support fixture 551, and a block 552, each of which is formed of aluminum, steel, or other like or similar substantially rigid material or combination of materials. Bracket 550 attaches to frame 210 of bicycle 541 between front and rear wheels 235 and 227 of bicycle 541, support fixture 551 attaches to bracket 550, block 552 attaches to support fixture 551, and forward and rearward stabilizing assemblies 501 and 502 attach to block 552, in accordance with the principle of the invention.

Referring to FIGS. 27-28 in relevant part, bracket 550 has opposed upper and lower surfaces 560 and 561, opposed front and rear ends 562 and 563, threaded openings 564 formed in front end 562 used to accept threaded fasteners to secure support fixture 551, a transverse seat 565 formed in upper surface 560 toward rear end 563 of bracket 550 and that extends between the opposed sides of bracket 550 and which is used to receive therein a portion of the frame a bicycle, an opening 566 near rear end 563 that extends through bracket 55 from lower surface 561 to seat 565 at upper surface 560 to receive a threaded fastener used to secure bracket 550 to the frame of a bicycle, and a transverse receiving area or recess 567 formed in upper surface 560 toward front end 562 of bracket 550 and that extends between the opposed sides of bracket 550 and which accepts the bottom bracket of a bicycle in the installation of bracket 550 to a bicycle.

Referring back to FIG. 31, lug 570 is affixed to frame 210, such as by welding or by forming frame 210 integrally with lug 570. Lug 570 is considered part of or otherwise an extension of frame 210 and seat 565 relates to lug 570 so as to permit lug 570 to be received by or otherwise to fit within seat 565. Bracket 550 is affixed to lug 570 of frame 210 with a threaded fastener denoted at 571 in FIGS. 26, 27, and 31, which is applied through opening 560 of bracket 550 and is threaded into a corresponding threaded opening formed in lug 570 and which is tightened through rotation to rigidly affix bracket 550 to frame 210 of bicycle 542 and thus to rigidly secure and locate bottom bracket 253 in recess 567 formed in base bracket 550. Bracket 550 can be rigidly affixed to lug 570 in other ways, such as with two or more threaded fasteners, one or more rivets, welding, a clamp, etc.

Looking to FIGS. 25-31, support fixture 551 is secured between bracket 550 and block 552. Referencing FIGS. 25-28 and 31 in relevant part, support fixture 551 has opposed upper and lower ends 580 and 581, and a pair of opposed, elongate, vertical, parallel, substantially coextensive slots 582 formed therethrough proximate to upper end 580. Upper end 580 of support fixture 231 is applied against front end 562 of bracket 550 registering slots 582 with threaded openings 564 formed in front end 562 of bracket 550. Threaded fasteners 586 in the form of threaded bolts are applied into and through slots 582 and are threaded into threaded openings 564 formed in front end 562 of bracket 550 and are then rotated and tightened to rigidly secure support fixture 551 to front end 562 of bracket 550. Support fixture 551 extends downwardly with respect to bracket 550 and frame 210 of bicycle 541 from upper end 580 to lower end 581, which is attached to block 552. Washers 587 encircle threaded fasteners 586 and are positioned between heads 586A of fasteners 586 and support fixture 551.

Block 552 has opposed front and rear ends 552A and 552B and is formed with a pair of forward upper and lower threaded openings 590A and 590B extending into front end 552A. Front end 552A is positioned directly against the back side of support fixture 551 proximate to lower end 581 of support fixture 551 opposite to lower surface 561 of bracket 550 registering upper and lower threaded openings 590A and 590B with a corresponding pair of upper and lower openings 591A and 591B formed through support fixture 551 near lower end 581. There is a lock plate 600 that has opposed, elongate, vertical slots 601 formed on either side of a central bolt-receiving opening 602. Lock plate 600 is applied directly against the front side of support fixture 551 registering bolt-receiving opening 602 with upper opening 591A and registering slots 601 with a corresponding pair of opposed threaded openings 604 formed in support fixture 551 on either side of upper opening 591A. Threaded fasteners 605 are applied into and through slots 601 of lock plate 600 and are threaded into threaded openings 604 and are then tightened via rotation to rigidly securing lock plate 600 to the front side of support fixture 551 near lower end 581. Slots 601 are vertically elongate and permit a user to adjust lock plate 600 up-and-down as needed in order to register or otherwise align bolt-receiving opening 602 with upper opening 591A before tightening down lock plate 600 with threaded fasteners 605.

Support fixture 551 is secured to block 552 with upper and lower threaded fasteners 607 and 608. Upper fastener 607 is applied into and completely through bolt-receiving opening 602 of lock plate 600 and is applied to upper opening 591A and is threaded into upper threaded opening 590A of block 552. Lower fastener 608 is applied to lower opening 591B and is threaded into lower threaded opening 590B. Upper and lower fasteners 607 and 608 are then tightened through rotation to rigidly secure support fixture 551 to block 552. As seen in FIG. 32, upper opening 591A is formed with a counterbore 609 into which is received head 607A of upper threaded fastener 607. Head 607A of upper fastener 607 is tightened against counterbore 609 to rigidly secure block 552.

Block 552 is rigidly secured to support fixture 551 proximate to lower end 581 of support fixture 551 underneath and in opposition to bracket 550 as shown in FIG. 31 thereby suspending block 552 below bottom bracket 253 and frame 210 of bicycle 541 below and underneath lower surface 561 of bracket 550. A washer 593 encircles lower threaded fastener 608 and is positioned between head 608A of lower threaded fastener 608 and support fixture 551. Connector assembly 503 may be readily detached from bicycle 541 by reversing the steps of installing connector assembly 503 onto bicycle 341 as described above.

Forward stabilizing assembly 501 attaches to block 552. The attachment between forward stabilizing assembly 501 and block 552 is a pivotal attachment or coupling to permit forward stabilizing assembly 501 to pivot or pivotally move or adjust at block 552 between a raised position with respect to bicycle 541 to disengage forward stabilizing assembly 501 from the ground over which bicycle 541 is driven to secure forward stabilizing assembly 501 from vehicle stabilization by forward stabilizing assembly 501, as shown in FIG. 39, when vehicle stabilization by forward stabilizing assembly 501 not required or needed, and a lowered position with respect to bicycle 541 to engage forward stabilizing assembly 501 with the ground over which bicycle 541 is driven to engage forward stabilizing assembly 501 for vehicle stabilization by forward stabilizing assembly 501, as shown in FIGS. 29, 30, 34, 36, and 37, when vehicle stabilization by forward stabilizing assembly 501 is required or needed.

Brace 519 has opposed inner and outer extremities 519A and 519B. Inner extremity 519A is directed toward collars 517, and outer extremity 519B is directed toward distal arms 516. A receiving area or gap 610 is defined between proximal arms 515 of forward support members 511A and 511B of fixture 510, and this receiving area or gap 610 extends and is defined between inner extremity 519A of brace 519 and collars 517 formed in inner ends 515A. Forward stabilizing assembly 501 is located under frame 210 of bicycle 541 and lower end 581 of support fixture 551 and front end 552A of block 552 are positioned in gap 610 locating the portions of proximal arms 515 extending from brace 519 to collars 517 on either side of support fixture 551 and block 552 under bottom bracket 253 of bicycle 541 as shown in FIG. 31. To form the pivotal coupling between forward stabilizing assembly 501 and block 552 of connector assembly 503, opposed threaded pivot bolts 611 are applied to collars 517 about which collars 517 can pivot between the raised and lowered positions of forward stabilizing assembly 501 and threaded pivot bolts 611 are threaded into corresponding, diametrically opposed threaded openings 614 (only one shown) formed in either side of block 552 between front and rear ends 552A and 552B of block 552, and threaded pivot bolts 613 are tightened via rotation securing collars 517 of fixture 510 to block 552 on either side of block 552 thereby securing fixture 510, and, in turn, forward stabilizing assembly 501, to block 552 of connector assembly 503.

Forward support members 511 of fixture 510 of forward stabilizing assembly 501 extend forwardly toward front wheel 235 and front end 211 of bicycle 541 from collars 517 to stabilizer wheels 518 carried by distal arms 516. Forward stabilizer assembly 501 is pivotally coupled to block 552 and is thus supported by block 552 at the pivotal coupling between fixture 210 of forward stabilizing assembly 501 and block 552. One forward support member 511A of forward stabilizing assembly 501 is positioned along the side 210A of bicycle 541 underneath frame 210 of bicycle 541, and the other forward support member 511B of forward stabilizing assembly 501 is positioned along the side 210B of bicycle 541 underneath frame 210 of bicycle 541. Forward support member 511A of fixture 210 of forward stabilizing assembly 501 supports one stabilizer wheel 518 of forward stabilizing assembly 501 along the side 210A of frame 210 proximate to, and outboard of, front wheel 235 of bicycle 541, forward support member 511B of fixture 210 of forward stabilizing assembly 501 supports the other stabilizer wheel 518 of forward stabilizing assembly 501 along the side 210B of frame 210 proximate to, and outboard of, front wheel 235 of bicycle 541, and stabilizer wheel 518 of forward support member 511A opposes stabilizer wheel 518 of forward support member 511B.

Like forward stabilizing assembly 501, rearward support members 530 of rearward stabilizing assembly 502 attach to block 552. The attachment between each of the rearward support members 530 of rearward stabilizing assembly 502 and block 552 is a pivotal attachment or coupling to permit rearward support members 530 to pivot or pivotally move or adjust at block 552 between raised and lowered positions with respect to bicycle 541. As a matter of illustration and reference, FIGS. 29 and 30 show rearward support members 530A and 530B as they would appear pivoted into a lower position, and it is to be understood that in FIG. 30 rear support member 530A is not shown as it is hidden behind rear support member 530B. FIGS. 34 and 35 show rearward support member 530B as it would appear pivoted into a raised position relative to bicycle 541, while rearward support member 530A is shown as it would appear pivoted into a lowered position relative to bicycle 541. FIG. 36 shows rearward support member 530A as it would appear pivoted into a raised position relative to bicycle 541, while rearward support member 530B is shown as it would appear pivoted into a raised position relative to bicycle 541. FIGS. 37 and 38 show rearward support member 530A as it would appear pivoted into a lowered position relative to bicycle 541, while rearward support member 530B is shown as it would appear pivoted into a lowermost position relative to bicycle 541. Rearward support members 530A and 530B are pivotally coupled independently to block 552 to permit independent pivotal movement of rearward support members 530A and 530B between their respective raised and lowered positions and also the lowermost positions such as demonstrated by rearward support member 530B in FIGS. 37 and 38.

Looking to FIGS. 26, 27, and 28 in relevant part, rearward stabilizing assembly 502 is located under frame 210 of bicycle 541. To pivotally couple rearward support members 530 to block 552 of connector assembly 503, heads 534 are located on either side of block 552 near rear end 552A of block 552 and opposed lower threaded bolts 620 are applied to lower through holes 534B about which heads 534 can pivot between the raised and lowered positions of rearward support members 530 and lower threaded bolts 620 are threaded into corresponding, diametrically opposed lower threaded openings 622 (only one shown) formed in either side of block 552 between threaded opening 614 and rear end 552B of block 552, and lower threaded bolts 620 and then tightened through rotation securing heads 534 to block 552 on either side of block 552 near rear end 552A of block 552 thereby securing rearward stabilizing assembly 502 to block 552 of connector assembly 503. Upper threaded bolts 624 are applied to upper through holes 534A and upper threaded bolts 624 are threaded into corresponding, diametrically opposed upper threaded openings 625 (only one shown) formed in either side of block 552 over lower threaded openings 622 and between threaded opening 614 and rear end 552B of block 552, and upper threaded bolts 625 are tightened via rotation securing upper threaded bolts 624 in place to block 522 while permitting upper threaded bolts 624 to run back-and-forth through upper through holes 534A in response to the pivoting of rearward support members 530A and 530B between their raised and lowered positions.

Looking to FIGS. 29 and 30, forward support members 511A and 511B of fixture 510 of forward stabilizing assembly 501 extend forwardly under frame 210 of bicycle 541 toward front wheel 235 and front end 211 of bicycle 541 from collars 517 to stabilizer wheels 518 carried by distal arms 516. One forward support member 511A of forward stabilizing assembly 501 is positioned along the side 210A of bicycle 541 underneath frame 210 of bicycle 541, and the other forward support member 511B of forward stabilizing assembly 501 is positioned along the side 210B of bicycle 541 underneath frame 210 of bicycle 541. Forward support members 511A and 511B of forward stabilizing assembly 501 are located on either side 210A and 210B of frame 210 of bicycle 541 underneath frame 210 of bicycle 541 positioning forward support members 511A and 511B so as to apply the wheels 518 of the wheeled ends of forward support members 511A and 511B against the ground over which bicycle 541 is driven on either side of front wheel 235 to permit the wheeled ends of forward stabilizing assembly 501 to wheelingly interact with the ground over which bicycle 541 is driven to stabilize bicycle 541 as bicycle 541 is driven over the ground. As such, that stabilizers in the form of wheels 518 of the wheeled ends 516B of forward stabilizing assembly 501 oppose one another on either of sides 210A and 210B of frame 210 of bicycle 541 and are located to concurrently roll over the ground over which bicycle 541 is driven such that front wheel 235 of bicycle 541 operates in the normal manner while wheels 518 of forward stabilizing assembly 501 are positioned against the ground over which bicycle 541 is ridden on either side of bicycle 541 in the lowered position of forward stabilizing assembly 501 such that forward stabilizing assembly 501 interacts with the ground on either side of bicycle 541 to stabilize bicycle 541 along front end 211 of bicycle 541 as it is driven to prevent bicycle 541 from tipping over, according to the principle of the invention.

Rearward support members 530A and 530B of rearward stabilizing assembly 502 extend rearwardly under frame 210 of bicycle 541 toward rear wheel 227 and rear end 212 of bicycle 541 from heads 534 to stabilizer wheels 538 carried by distal arms 516. One rearward support member 530A of rearward stabilizing assembly 502 is positioned along the side 210A of bicycle 541 underneath frame 210 of bicycle 541, and the other rearward support member 530B of rearward stabilizing assembly 502 is positioned along the side 210B of bicycle 541 underneath frame 210 of bicycle 541. Rearward support member 530A of rearward stabilizing assembly 502 supports one stabilizer wheel 538 of rearward stabilizing assembly 502 along the side 210A of frame 210 proximate to, and outboard of, rear wheel 227 of bicycle 541, rearward support member 530B of rearward stabilizing assembly 502 supports the other stabilizer wheel 538 of rearward stabilizing assembly 502 along the side 210B of frame 210 proximate to, and outboard of, rear wheel 227 of bicycle 541, and stabilizer wheel 538 of rearward support member 530B opposes stabilizer wheel 538 of rearward support member 530B. Rearward support members 530A and 530B of rearward stabilizing assembly 502 are located on either side 210A and 210B of frame 210 of bicycle 541 underneath frame 210 of bicycle 541 positioning rearward support members 530A and 530B so as to apply the wheeled ends of rearward support members 530A and 530B against the ground over which bicycle 541 is driven on either side of rear wheel 227 to permit the wheeled ends of rearward stabilizing assembly 502 to wheelingly interact with the ground over which bicycle 541 is driven to stabilize bicycle 541 as bicycle 541 is driven over the ground. As such, wheels 538 at the wheeled ends 532B of rearward support members 530A and 530B of rearward stabilizing assembly 502 are located to roll over the ground over which bicycle 541 is driven on either side of bicycle 541 such that rear wheel 227 of bicycle 541 operates in the normal manner while wheels 538 of rearward stabilizing assembly 502 are positioned against the ground over which bicycle 541 is ridden on either side of bicycle 541 in the lowered positions of rearward support members 530A and 530B of rearward stabilizing assembly 502 such that rearward stabilizing assembly 502 interacts with the ground on either side of bicycle 541 to stabilize bicycle 541 along rear end 212 of bicycle 541 as it is driven to prevent bicycle 541 from tipping over, according to the principle of the invention.

Forward support member 511A and rearward support member 530A are disposed proximate to and extend along the side 210A of frame 210 of bicycle 341 from wheeled end 516B of forward support member 511A alongside front wheel 235 of bicycle 541 to wheeled end 532B of rearward support member 530A alongside rear wheel 227 of bicycle 541, whereby distal arm 516 of forward support member 511A extends outwardly from proximal arm 515 of forward support member 511A and side 210A of frame 210 of bicycle 541 to wheeled end 516B, which is disposed or otherwise located proximate to and outboard of front wheel 235 of bicycle 341, and whereby distal arm 532 of rearward support member 530A extends outwardly from proximal arm 531 of rearward support member 530A and side 210A of frame 210 of bicycle 541 to wheeled end 532B, which is disposed or otherwise located proximate to and outboard of rear wheel 227 of bicycle 541. With this arrangement, wheel 518 of wheeled end 516B of forward support member 511A is in-line with respect to wheel 538 of wheeled end 532B of rearward support member 530A. Forward support member 511A of forward stabilizing assembly 501 along the side 210A of bicycle 541 and rearward support member 530A of rearward stabilizing assembly 502 along the side 210A of bicycle 541 cooperate as a right-side stabilizer/stabilizing assembly along the side 210A of bicycle 541, which is the right side of bicycle 541.

Forward support member 511B and rearward support member 530B are disposed proximate to and extend along the side 210B of frame 210 of bicycle 341 from wheeled end 516B of forward support member 511B alongside front wheel 235 of bicycle 541 to wheeled end 532B of rearward support member 530B alongside rear wheel 227 of bicycle 541, whereby distal arm 516 of forward support member 511B extends outwardly from proximal arm 515 of forward support member 511B and side 210B of frame 210 of bicycle 541 to wheeled end 516B, which is disposed or otherwise located proximate to and outboard of front wheel 235 of bicycle 341, and whereby distal arm 532 of rearward support member 530B extends outwardly from proximal arm 531 of rearward support member 530B and side 210B of frame 210 of bicycle 541 to wheeled end 532B, which is disposed or otherwise located proximate to and outboard of rear wheel 227 of bicycle 541. With this arrangement, wheel 518 of wheeled end 516B of forward support member 511B is in-line with respect to wheel 538 of wheeled end 532B of rearward support member 530B. Forward support member 511B of forward stabilizing assembly 501 along the side 210B of bicycle 541 and rearward support member 530B of rearward stabilizing assembly 502 along the side 210B of bicycle 541 cooperate as a left-side stabilizer/stabilizing assembly along the side 210B of bicycle 541, which is the left side of bicycle 541.

When mounted to bicycle 341 according to this disclosure, the described left- and right-side stabilizer assemblies oppose and are the minor image of one another, and are located on the opposite sides 210A and 210B, respectively, of frame 210 and underneath frame 210 so as not to interfere with the normal pedaling action of pedals 251 and crank arms 251, which takes place along the outer side of the described left- and right-side stabilizer assemblies. With reference to FIG. 29, front wheel 235 of bicycle 341 rotates about axis of rotation denoted at 390, rear wheel 227 rotates about axis of rotation denoted at 391, front or forward stabilizer wheels 518 of forward stabilizing assembly are positioned proximate to axis of rotation 390 of front wheel 235, and rear or rearward stabilizer wheels 538 of rearward stabilizing assembly 502 are positioned proximate to axis of rotation 391 of rear wheel 227.

Of course, in the use of bicycle 541 in its normal manner with stabilization apparatus 500 attached thereto as explained above, front and rear wheels 235 and 227 of bicycle 541, the two wheeled ends of forward stabilizing assembly 501 and the two wheeled ends of rearward stabilizing assembly 502 concurrently interact with the ground over which bicycle 341 is driven to permit forward and rearward stabilizing assemblies 501 and 502 to work in accordance with their intended purpose which is to cooperate together to stabilize bicycle 541 as it is driven over the ground by preventing bicycle 541 from tipping over on one side or the other. And so stabilization apparatus 500 is constructed, arranged, and sized to fit onto bicycle 541 to function in this way. The four wheeled ends of stabilization apparatus 500 concurrently interact with the ground over which bicycle 541 is driven to form a four-point wheeled footprint that engage against and wheelingly interact with the ground over which bicycle 541 is ridden stabilizing bicycle 541 during the normal use thereof to assist users that are uncoordinated or may suffer from a balance disorder in safely riding bicycle 541.

Stabilization apparatus 500 is designed to be removably attached to any bicycle, and bicycles come in different sizes and shapes and have different clearances between the frame and the ground over which the bicycle is ridden. As such, connector assembly 262 is configured to permit adjustment of the pivotal connecting points of forward and rearward stabilizing assemblies 501 and 502 at block 552 between a raised position toward frame 210 and a lowered position away from frame 210 as shown in FIG. 22, and a lowered position away from frame 210. This adjustment is provided by slots 582 formed in support fixture 551. Slots 582 of support fixture 551 function identically to that of slots 352 of support fixture 321 of apparatus 202, and the reciprocal adjustment of support fixture 551 with slots 582 is carried out in the exact same manner as the adjustment of support fixture 321 with slots 352 of support fixture 321 discussed in detail in connection with apparatus 202.

Referring to FIGS. 28 and 29, fixture 510 of forward stabilizing assembly 501 pivots between its raised and lowered positions at collars 517 about a pivot axis 517A defined by collars 517, which pivot axis 517A extends transversely with respect to frame 210 of bicycle 541 between front and rear wheels 235 and 227 and is substantially parallel with respect to axis 390 of rotation of front wheel 235, axis 391 of rotation of rear wheel 227, and axis 253A of rotation of bottom bracket 253 that is located above and that opposes pivot axis 571A of forward stabilizing assembly 501. Rearward support members 530A and 530B of rearward stabilizing assembly 502 pivot between their raised and lowered positions at lower threaded bolts 620 about a common pivot axis 620A defined by lower threaded bolts 620, which pivot axis 620A extends transversely with respect to frame 210 of bicycle 541 between front and rear wheels 235 and 227 and is located just rearward of pivot axis 517A and is substantially parallel with respect to pivot axis 517A, axis 390 of rotation of front wheel 235, axis 391 of rotation of rear wheel 227, and axis 253A of rotation of bottom bracket 253 that is located above and that opposes pivot axis 620A of rearward support members 530A and 530B of rearward stabilizing assembly 502.

Rearward support members 530A and 530B are each mounted for independent pivotal movement to block 552 for independent pivotal movement between their raised and lowered positions and also the lowermost position as demonstrated by rearward support member 530B in FIGS. 37 and 38. This permits rearward support members 530A and 530B to pivotally displace about pivot axis 620A as bicycle 541 is driven over the ground to absorb bumps and divots or depressions in the ground over which bicycle 541 is driven. As rearward support members 530A and 530A pivot about pivot axis 620A, upper threaded bolts 624 translate back-and-forth through the corresponding elongated through holes 534A, which interact with upper threaded bolts 624 to limit the uppermost and lowermost positions of rearward support members 530A and 530B. As a matter of example, in FIG. 35 rearward support member 530B is shown as it would appear in its raised position, which is the uppermost raised position of rearward support member 530B, and FIG. 40 is a section view taken along line 40-40 of FIG. 35 which illustrates upper threaded bolt 624 as it would appear functioning as an abutment interacting with a rear closed end 630 of through hole 534A by abutting directly against rear closed end 630 of through hole 534A limiting the rearward support member 530B from pivoting upwardly beyond its raised position, which, in this example, is the uppermost raised position of rearward support member 530B. The lowered position of rearward support member 530B, as with rearward support member 530A, is between the raised/uppermost position of rearward support member 530B and the lowermost position of rearward support member 530B. In FIG. 38 rearward support member 530B is shown as it would appear in its lowermost position, and FIG. 40 is a section view taken along line 40-40 of FIG. 35 which illustrates upper threaded bolt 624 as it would appear functioning as an abutment interacting with a front closed end 631 of through hole 534A by abutting directly against front closed end 631 of through hole 534A that is opposite to rear closed end 630 of through hole 534A limiting the rearward support member 530B from pivoting downwardly beyond its lowermost position. The arrange of, and the interaction between, through hole 534 and upper threaded bolt 624 forms an abutment assembly coupled between block 552 of connector assembly 503 and rearward support member 530B which limits movement of rearward support member 530B between its raised and lowermost positions. This discussion of rearward support member 530B applies in every respect to rearward support member 530A as they are identical.

As explained above, fixture 210 of forward stabilizing assembly 501 is mounted to block 552 of connector assembly 503 for pivotal movement at block 552 between a raised position with respect to bicycle 541 to disengage the wheels 518 of the wheeled ends of forward stabilizing assembly 501 from the ground over which bicycle 541 is driven to secure forward stabilizing assembly 501 from vehicle stabilization, as shown in FIG. 39, when vehicle stabilization by forward stabilizing assembly 501 is not needed or required by a rider of bicycle 541, and a lowered position with respect to bicycle 541 to engage the wheels 518 of the wheeled ends of forward stabilizing assembly 501 with the ground over which bicycle 541 is driven to engage forward stabilizing assembly 501 for vehicle stabilization, as shown in FIGS. 29, 30, 34, 36, and 37, when vehicle stabilization by forward stabilizing assembly 501 is needed or required by a rider of bicycle 541. And so fixture 210 movable between a raised position toward 210 frame of bicycle 541 away from the ground over which bicycle 541 is driven when vehicle stabilization by forward stabilizing assembly 501 is not required, such as by a rider riding bicycle 541, and a lowered position away from frame 210 of bicycle 541 and toward the ground over which bicycle 541 is driven when vehicle stabilization by forward stabilizing assembly 501 is required, such as by a rider riding bicycle 541. According to the principle of the invention, lock assembly 504 is coupled between frame 210 and fixture 210 of forward stabilizing assembly 501, and in the lowered position of fixture 210 of forward stabilizing assembly 501 the lock assembly 504 is adjustable between an unlocked position as shown in FIG. 33 releasing fixture in the lowered position thereof allowing fixture 541 to pivot/move from its lowered position to its raised position, and a locked position shown in FIG. 32 locking fixture in the lowered position thereof to engage the wheels 518 of the wheeled ends of forward stabilizing assembly 501 with the ground over which bicycle 541 is driven to engage forward stabilizing assembly 501 for vehicle stabilization, as shown in FIGS. 29, 30, 34, 36, and 37, and preventing fixture 210 from moving from the lowered position thereof to the raised position thereof.

Referring in relevant part to FIGS. 25-33, lock assembly 504 and its operation will now be discussed in detail. Lock assembly 504 consists of a bolt assembly 700, a support 701 for bolt assembly 700, a guide block 702, and a lever 703 operatively coupled to bolt assembly 700 for operating bolt assembly 700, namely, adjusting bolt assembly 700 between its locked and unlocked positions and for raising and lowering fixture 210 between its raised and lowered positions. Bolt assembly 700, support, and guide block 702 are carried by fixture 210, and lever 703 is carried by frame 210 of bicycle 541.

With specific reference to FIGS. 32 and 33, bolt assembly 700 consists of a bolt 710 having a head part 710A and an opposite tail part 710B, and a bolt housing 711. Bolt housing 711 has opposed front and rear ends 711A and 711B, and bolt 710 is mounted partially within bolt housing 711 through front end 711A for reciprocal movement in the direction indicated by double arrowed line 712 between an extended locked or locking position shown in FIG. 32 and a retracted unlocked or unlocking position shown in FIG. 33. Bolt 710 has opposed head and tail parts 710A and 710B, and an intermediate part 710C therebetween. Intermediate part 710C extends through an intermediate wall 714 formed inside bolt housing 711, and head part 710A of bolt 710 is located along one side of intermediate wall 714 toward front end 711A of bolt housing 711, and tail part 710B of bolt 710 is located on the other side of intermediate wall 714 toward rear end 711B of bolt housing 711. A conventional compression spring 716 within bolt housing 711 encircles intermediate portion 710C of bolt 710 between intermediate wall 714 and head part 710A of bolt 710 and acts between intermediate wall 714 and head part 710A biasing bolt 710 away from its unlocked/retracted position and toward its locked/extended position.

A face plate 720 has a central bolt-receiving opening 721 and is affixed to a back side of support 701 with opposed pins 722, and support 701 is formed with a cylindrical central opening 724 that registers or otherwise aligns with bolt-receiving opening 721 of face plate 720. Front end 711A of bolt housing 711 is a cylindrical collar, which is press fit into opening 724 formed through support 701 in a direction from a front side of support 701, and head part 710A extends partially outward from front end 711A of bolt housing 711 and extends through bolt-receiving opening 721 of face plate 720. There is a clearance shown between front end 711A of bolt housing 711 and opening 724 of support 701 for illustrative purposes with the understanding that there is a rigid, press fit between front end 711A of bolt housing 711 and opening 724 of support 701.

A pair of opposed, elongate, parallel slots 730 are formed through brace 519 near inner end 519A. Slots 730 are positioned between and are parallel with respect to proximal arms 515 of fixture 210. The underside of support 701 is applied against the top side of brace 519 over slots 730 near inner end 519A between proximal arms 515 locating bolt assembly 700 between proximal arms 515 such that bolt assembly 700 located above the top side of brace 519 and is parallel with respect to proximal arms 515 of fixture 210 and extends rearwardly in a direction from front end 711A of bolt housing 711 at support 701 located near inner end 519A of brace 519 to rear end 711B of bolt housing 711 directed toward outer end 519B of brace 519. Support 701 is rigidly secured in place to brace 519 with threaded fasteners 731 directed through slots 730 from the underside of brace 519 and which are threaded into corresponding threaded openings (not shown) formed in the underside of support 701 and threaded fasteners 731 are tightened via rotation tightening down threaded fasteners 731 thereby rigidly securing support 701 to the top side of brace 519 near inner end 519A and, in turn, rigidly securing bolt assembly 700 in place over the top side of brace 519.

In the lowered position of forward stabilizing assembly 501, head part 710A of bolt 710 opposes and registers with or is otherwise aligned with bolt-receiving opening 602 formed in lock plate 600 rigidly affixed to support fixture 551 as shown in FIGS. 32 and 33. In the extended/locking position of bolt 710 in the lowered position of forward stabilizing assembly 501 as shown in FIG. 32, head part 710A is extended into and is received by bolt-receiving opening 602 locking lock plate 600 to head part 710A of bolt 710 securing/engaging lock assembly 504 between forward stabilizing assembly 501 and connector assembly 503 securing forward stabilizing assembly 501 in its lowered vehicle-stabilizing position to permit forward stabilizing assembly 501 to engage the wheels 518 of the wheeled ends of forward stabilizing assembly 501 with the ground over which bicycle 541 is driven to engage forward stabilizing assembly 501 for vehicle stabilization while concurrently preventing forward stabilizing assembly from moving out of its lowered position and into its raised position. In the retracted/unlocking position of bolt 710 in the lowered position of forward stabilizing assembly 501 as shown in FIG. 33, head part 710A is retracted out of bolt-receiving opening 602 of lock plate 602 releasing bolt 710 from lock plate 602 releasing/dis-engaging lock assembly 504 from connector assembly 503 to permit forward stabilizing assembly 501 to pivot/move from its lowered vehicle-stabilizing position to its raised position to disengage the wheels 518 of the wheeled ends of forward stabilizing assembly 501 from the ground over which bicycle 541 is driven to secure forward stabilizing assembly 501 from vehicle stabilization. Lever 703 is operatively coupled to bolt assembly 700 for operating bolt assembly 700, namely, adjusting bolt assembly 700 between the extended/locked position of bolt 710 and the retracted/unlocked position of bolt 710, and also for raising and lowering fixture 210 between its raised and lowered positions, as will now be discussed.

Lever 703 is an operator interface and is used by the rider of bicycle 541 for operating bolt assembly 700 in the manner discussed above. Looking to FIG. 30, lever 703 is a conventional hand-operated lever secured to frame 210 with a conventional bracket 734. In this embodiment, lever 703 is secured to top tube 220 of frame 210 near head tube 222 to provide convenient access to lever 703 from a rider riding bicycle 541. Lever 703 is operatively coupled to bolt assembly 700 with a cable 740 coupled between lever 703 and tail part 710B of bolt 710 as seen in FIGS. 32 and 33. Cable 703 extends between lever 703 and tail part 710B of bolt 710 and has an upper end 740A attached to lever 703 via conventional welding or crimping techniques and an opposed lower end 740B as shown in FIGS. 32 and 33 that extends into and through rear end 711B of bolt housing 711 and is affixed to tail part 710B via conventional welding or crimping techniques.

An opening 750 is formed through brace 519 near inner end 519A. The underside of guide block 702 is applied against the top side of brace 519 over opening 750 at outer end 519A and guide block 702 is received directly against rear end 711B of bolt housing 711. Guide block 702 is rigidly secured in place to brace 519 with a threaded fastener 748 provided with an applied washer 748A and which is directed through opening 750 from the underside of brace 519 and which is threaded into corresponding threaded openings (not shown) formed in the underside of guide block 702 and threaded fastener 748 is tightened via rotation tightening down threaded fastener 748 thereby rigidly securing guide block 702 to the top side of brace 519 at outer end 519B.

A cable guide 751 and a pair of cable stays 752 are formed in a side of guide block 702. Cable stays 752 are conventional and are threadably secured into a pair of corresponding threaded openings formed on the inner side of cable guide 751 between rear end 711B of bolt housing 711 and cable guide 751. Cable 740 is applied to cable guide 751, and is retained in cable guide 751 with cable stays 752.

Cable 740 runs through a cable bracket assembly 760 secured to frame 210 of bicycle 541 between lever 703 and guide block 702. Cable bracket assembly 760 is secured to down tube 221 under lever 703 and over guide block 702 in the present embodiment as seen in FIG. 30, and cable 740 extends vertically between cable bracket assembly 760 and guide block 702. Cable bracket assembly 760 consists of opposed, identical clamp parts 761 that are received over either side of down tube 222 and are secured together with threaded fasteners 762 in the form of threaded bolts, which are tightened via rotation clamping down tube 221 by and between clamp parts 761. A conventional cable nipple 764 is threaded into a threaded opening 765 formed in a supporting lug 767 that is, in turn, threaded onto a threaded post 768 formed in one of the clamp parts 761. Cable 740 extends concurrently through threaded opening 765 and nipple 764 between lever 703 and guide block 702 and holds the length of cable 740 between cable bracket assembly 760 and guide block 702 vertically upright.

In the lowered position of forward stabilizing assembly 501 in the extended/locked position of bolt 710 as shown in FIG. 32, lever 703 may be moved along a lever stroke path from an open position thereof as shown in FIGS. 29, 30, 34, 36, and 37 to a closed position thereof as shown in FIG. 39, which shortens the length of cable 740 between cable bracket assembly 760 and guide block 702 causing cable 740 to act on bolt 710 in the direction indicated by arrowed line 770 in FIG. 33 overcoming the bias applied by spring 716 displacing bolt 710 from its extended/locked position of FIG. 32 to its retracted/unlocked position of FIG. 33 releasing forward stabilizing assembly 501 from its locked position to allow stabilizing assembly 501 to be pivoted from its lowered position to its raised position as may be required or desired a rider riding bicycle 541. As lever 703 is moved along its lever stroke path from its open position toward its closed position as shown in FIG. 39, at an intermediate position of lever 703 between its open position and its closed position spring 716 becomes fully overcome and compressed between head part 710A of bolt and intermediate wall 714 of bolt housing 711 and the length of cable 740 running from tail part 710B of bolt 710 and through cable guide 751 of guide block 702 and from guide block 702 to cable bracket assembly 760 and from cable bracket assembly 760 to lever 703 is pulled tight or otherwise rigidified between bolt 710 and lever 703 rigidly coupling lever 703 to forward support assembly 501 at bolt 710, whereby continued movement of lever 703 toward and into its closed position as shown in FIG. 39 acts on and picks up or otherwise pulls forward stabilizing assembly 501, namely, fixture 210 and its attached components, upwardly in the direction indicated by arrowed line 771 in FIG. 39 pivoting forward stabilizing assembly 501 at its pivotal attachment to block 552 from the lowered position of forward stabilizing assembly 501 to the raised position of forward stabilizing assembly 501 as shown in FIG. 39.

To move forward stabilizing assembly back to its lowered position and to relock lock assembly 504 between forward stabilizing assembly 501 and connector assembly 503 to secure forward stabilizing assembly 501 back into its lowered position to secure forward stabilizing assembly 501 for vehicle stabilization, the foregoing operation for unlocking forward stabilizing assembly 501 from its lowered position and raising forward stabilizing assembly 501 from its lowered position to its raised position need only be reversed. Specifically, lever 703 need only be released or otherwise moved along its lever stroke path from its closed position as shown in FIG. 39 to its open position as shown in FIGS. 29, 30, 34, 36, and 37, causing the length of length of cable 740 running from tail part 710B of bolt 710 and through cable guide 751 of guide block 702 and from guide block 702 to cable bracket assembly 760 to lengthen resulting in the pivoting of forward stabilizing assembly 501 at the pivotal connection of forward stabilizing assembly 501 to block 552 from its raised position to its lowered position away from frame 210 of bicycle 541 and toward and against the ground over which bicycle 541 is ridden registering head part 710A of bolt 710 with respect to bolt-receiving opening 602 of lock plate 602 as shown in FIG. 33. The continued releasing of lever 703 along its stroke path from the closed position of lever 703 to the open position of lever 703 in the lowered position of forward stabilizing assembly 501 releases spring 716 causing spring 716 to act between head part 710A of bolt 710 and intermediate wall 714 of bolt housing 711 displacing bolt 710 in the direction indicated by arrowed line 772 moving bolt 710 from its retracted/unlocking position as shown in FIG. 33 to its extended/locking position as shown in FIG. 32 causing forward stabilizing assembly 501 to be once again locked into is lowered vehicle-stabilizing position, in accordance with the principle of the invention. Cable 740 reciprocates back and forth in response to movement of lever 703 along its lever stroke path between its open and closed positions. To reduce cable friction along guide block 702 that could damage cable 740, a protective sheath 780 set into cable guide 751 is applied around cable 740 as best seen in FIGS. 31-33.
